1. A hand drying system for a lavatory, the hand drying system comprising:
- a blower housing that includes a blower that is configured to generate airflow within an air chamber, wherein the blower includes a magnetic motor, and a propeller magnetically coupled to the magnetic motor;
an exhaust vent configured to be secured to the lavatory, wherein the exhaust vent defines an air outlet; and
a conduit having a first end in fluid communication with the air chamber and a second end in fluid communication with the air outlet, wherein the conduit distally locates the blower housing from the lavatory.

Abstract
A hand drying system and method for a lavatory includes a blower housing that includes a blower that is configured to generate airflow within an air chamber. An exhaust vent is configured to be secured to the lavatory. The exhaust vent defines an air outlet. A conduit includes a first end in fluid communication with the air chamber and a second end in fluid communication with the air outlet. The conduit distally locates the blower housing from the lavatory.

11. A hand drying method for a lavatory, the hand drying method comprising:
-
securing an exhaust vent having an air outlet to the lavatory; fluidly coupling a first end of a conduit to an air chamber of a blower housing; coupling acoustic insulation to the blower housing; disposing at least one first acoustic dampening barrier within the air chamber; disposing at least one second acoustic dampening barrier within the conduit fluidly coupling a second end of the conduit to the air outlet of the exhaust vent; distally locating the blower housing from the lavatory by the fluidly coupling; and generating airflow within the air chamber of the blower housing with a blower. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A vehicle comprising:
-
an internal cabin; a lavatory within the internal cabin, wherein the lavatory defines an internal space; and a hand drying system for the lavatory, the hand drying system comprising; a blower housing that includes a blower that is configured to generate airflow within an air chamber, wherein the blower includes a magnetic motor, and a propeller magnetically coupled to the magnetic motor; an exhaust vent secured to the lavatory, wherein the exhaust vent defines an air outlet that is in fluid communication with the internal space of the lavatory; a conduit having a first end in fluid communication with the air chamber and a second end in fluid communication with the air outlet, wherein the conduit distally locates the blower housing from the internal space of the lavatory; acoustic insulation coupled to the blower housing; at least one first acoustic dampening barrier disposed within the air chamber; at least one second acoustic dampening barrier disposed within the conduit, wherein the acoustic insulation, the at least one first acoustic dampening barrier, and the at least one second acoustic dampening barrier reduce noise generated by the blower; a heating coil disposed within the conduit, wherein the heating coil is configured to heat the airflow before the airflow passes through the air outlet into the internal space of the lavatory, wherein the heating coil is positioned proximate to the second end of the conduit; an activation sensor configured to detect a presence of a hand within an activation zone and output a presence signal, wherein the blower is configured to be activated when the activation sensor detects the presence of the hand within the activation zone; and a dryer control unit in communication with the blower, the heating coil, and the activation sensor, wherein the dryer control unit is configured to control operation of the hand drying system. - View Dependent Claims (19, 20)
